Thread: Trannyman95 Please help! 2-3 up shift late and no show.

I live In Houston, Texas but I am writing from and have been be in Austin for the past 4 1/2 weeks.

I have had my 4T65E HD MN7 recently rebuilt. There had always been a slight shutter at launch that was barely detectible "as long as I babied the throttle pedal" all the way through the 1-2, up shift. Also, a little more recently, "DELAYED REVERSE ENGAGE, AFTER GEAR SHIFTER CHANGE". More recently, "NO OVERDRIVE", possibly also "NO FOURTH". This was all true before the rebuild of my 2000 4T65E HD XBB. The rebuild came from an individual who came "highly recommended" by my mechanic, Evan McDaniel, named James (I know).

My transmission was out of the car for 3 weeks, (awaiting parts to arrive). There were long periods of wait (sometimes 3 days) between call backs and when James finally did call back, the responses that came were short and sweet, "IT'S A SPRAG", "Waiting on parts to arrive", …ect. I spent much of my "down" time looking over this site and reading various postings and familiarizing my self with some of the regularly posting members. I have come to trust the Trannyman95 from reading multiple postings by him so if the Tranneyman95 is reading, I could really use any suggestions and or directions, please help, lol.

There is still a "BAD SHUTTER" starting at launch through 1st gear and all the way to the 1-2 up shift. The 1-2 shift also seems late (at no greater than 4500 rpm). No shutter though, from 2nd gear up, but the 2-3 up shift, seems late as well (at no greater than 4500 rpm). In fact, on one occasion, the 2-3 up shift, still had not arrived at 4500 rpm and had to back off, “just under” 5000 rpm, so it that it would never be in danger of redlining at 5500 rpm.

I was charged $460.00 down to cover parts and I paid the balance to pickup the car $1,300.00, on total completion of the work, $1,760.00. Please help! Does this sound like normal post rebuild behavior for a 4T65E MN7 XBB. Am I just being an unreasonable customer? If anyone has comments and \or suggestions they will be appreciated and graciously recieved. Please don't be shy if you think my driving could be the problem or even part of the problem. I really feel the need for resolution of this matter, one way or another and I want to get it right. Thanks for reading!

Short answer is the trans rebuild was done very poorly.

Ask him these questions

1) what valve body work did he do and what sensors did he replace (make sure you ask for exact specifics and write it all down)

2) Ask him if he replaced the input clutch piston and if not asked him if he addressed the inner lip wear issue and how he did that.

3) Also ask him if he just did a standard clutch pack configuration with all new frictions and newsteels.

Report back what he tells you, but make sure he is very specific on the valve body. When you post back I'll see if he addressed all the major concern issues that should be addressed with a rebuild.

supercharged99gse... i had this problem before and it turned out to be a vacuum leak. which will throw a TPS code.. check all vac lines especially the T boot connector under the SC snout.
